Architecture-Based Transformation of a Large Enterprise
Hans Gyllstrom, Enterprise Design Group
This talk presented observations and insights gleaned from leading transformations to a better state over the past 10 years or more.
Case study of transformation of a large Australian bank. CEO wanted to be able to say: I’ll never buy another data center, rack, server, storage, or network device; never get locked into proprietary hardware; tell teams it will be weeks to get them new hardware; pay up-front for infrastructure that may not be used; implement internal solutions for common problems when an equivalent commodity cloud solution is available. Implemented an IT agile operating model.
Transformation: from current state to target state via a migration path involving numerous intermediate state.
Architecture comprises decisions on structure. Period.
